Griffith's Gnat

The Griffith’s Gnat is a versatile little guy.  It can imitate a midge cluster of mating flies or an adult single midge – depending on size.  I have fished it when trout have been finicky and unresponsive to BWO patterns, and I want to give them a look at a different pattern.  It works well as a second fly, trailing off of another dry.  Fish seem to like it in slower, flat water and riding low in the foam.
